INITIALIZATION

Network Topology

          NUT(Client)
          |           
          |                        
Link0   --+--------+------------------------ 3ffe:501:ffff:100::/64
                   |
                   |          
                   TN(Server)

Verification Points

   On receipt of a valid Router Advertisement, 
   a host copies the value of the advertisement's M bit
   into ManagedFlag. If the value of ManagedFlag changes from FALSE to
   TRUE, and the host is not already running the stateful address
   autoconfiguration protocol, the host should invoke the stateful
   address autoconfiguration protocol, requesting both address
   information and other information.  If the value of the ManagedFlag
   changes from TRUE to FALSE, the host should continue running the
   stateful address autoconfiguration, i.e., the change in the value of
   the ManagedFlag has no effect.  If the value of the flag stays
   unchanged, no special action takes place. In particular, a host MUST
   NOT reinvoke stateful address configuration if it is already
   participating in the stateful protocol as a result of an earlier
   advertisement.

TEST PROCEDURE



       NUT      TN
        |       |
        |       | NUT has been configured with IPv6 address,
        |       | and request stateless DHCPv6 service
        |       |
        | <---- |RA with O=0 
        |       |
        | ----> |Information-request w/Option Request option/23,24 (2*)
        |       |  if NUT send Information-request, skip to ***
        |       |
        | <---- |RA with O=1 
        |       |
        | ----> |Information-request w/Option Request option/23,24 (4*)
        |       |
        | <---- |RA with O=0 ***
        |       |
        | ----->|Information-request w/Option Request option/23,24 (6*)
        |       |

JUDGEMENT


  
  (2*)PASS: NUT transmits Information-request to TN.
  (4*)PASS: NUT transmits Information-request to TN.
  (6*)PASS: NUT transmits Information-request to TN.
